Title: Stereo focus switching device of x-ray tube
Inventor: FURUYAMA MAKOTO
IPC: H01J35/12
Filed: 1989-04-27
Abstract: PURPOSE:To simplify the circuit used in the device stated in the title while using a high pressure vacuum tube such as a tetrode and the like by compensating the 'ON' voltage of each high pressure vacuum tube by means of partial pressure resistance of a bias power source, and connecting a grid and the minus side of a high pressure generator together. CONSTITUTION:When an X-ray focus control output is provided to a tetrode 40, the tetrode 40 is turned on and a current is caused to flow through a closed loop LP1, and the tetrode 40 has a voltage between its anode and cathode. Because this voltage is lower than the voltage at each end of a resistance 25, the diode 23 is turned on and a current is caused to flow through a closed loop LP2, and a bias voltage between an A side cathode 4 and a grid 3 is reduced to about 0V. An X-ray is thereby exerted from the A-side focus 42 of a stereo X-ray tube 1. The tetrode 40 is cut off by cutting of an X-ray focus control output simultaneously with finish of a high pressure output generated by an X-ray high pressure generator 31, and a bias voltage is applied which is positive between the grid to A side cathodes of the stereo X-ray tube 1 and which is negative at the grid, and the A side focus 42 of the X-ray tube 1 is cut off so that the X-ray is interrupted.

Title: Brake device for vehicle
Inventor: SAWADA MAMORU
IPC: B60T8/48
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To provide a brake device for a vehicle which can improve braking performance without causing any rear wheel precedent locking. SOLUTION: In a braking time ('YES' in S2000), if a wheel speed of a right rear wheel is higher by the predetermined value or more than a wheel speed of a left front wheel ('YES' in S3000) and antiskid control is not carried out for the right rear wheel, discharge in a pump is carried out (S4000), and because of existence of a proportional control valve, a brake fluid pressure increased higher than that on the master cylinder side works on a wheel cylinder for the right rear wheel, so that a braking force working on the right rear wheel is rapidly increased. Therefore, a wheel speed of the right rear wheel is rapidly reduced so as to be brought close to a speed of the left front wheel.  Consequently, sufficient braking force is generated for the rear wheels before a driver presses a brake pedal deeply, so that high braking performance can be exhibited without causing any rear wheel precedent locking.

The in-air insulation gap between the insulator 26, a steel tower, and the jumper wire 18 in the upper phase is retained sufficiently. When a surge current due to lightening shock flows through a power transmission line 15, the current is flashed over to the discharge electrode 36 on the grounded side via the jumper wire 18 and the discharge electrode 23 on the charge side to flow through a current restricting element 32 inside the insulator 26, so as to flow to the steel tower via a support arm 1 to be then discharged. The continuous current to be generated thereafter is shut by the element 32 and the in-air discharge gap G. Thereby the in-air insulation gap is secured to allow adaptation to an existing steel tower.

Filed: 1987-05-04
Abstract: PURPOSE:To certainly prevent malfunction of circuit element due to a leakage current, enhance reliability of operation under a high temperature condition and widen applicable temperature range by cancelling a leakage current generated under high temperature condition and a compensation current obtained from the other leakage current under the same condition. CONSTITUTION:Under a room temperature, a transistor 2 is caused to make adequate amplifying operation by closing a switch 12. In this case, even when operation of transistor 2 is ceased by opening the switch 12, a leakage current IL flows to a semiconductor substrate 15 from the base of transistor 2 and there by the transistor 2 demonstrates abnormal conductive condition. Therefore, in case the amplifying operation is required under a high temperature condition, if a leakage current IL is generated in the transistor 2, a compensating current by the leakage currents IL1, IL2 generated from the transistors 30, 32 is applied to the base B of transistor 2. Thereby, malfunction by the leakage current IL of transistor 2 can be prevented and reliability of operation under high temperature can be enhanced.
